IMPROVEMENT IN SKATES.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, THOMAS LOVELIDGE and Jens Gnmnnon, of Philadelphia, Pennsylvania, have invented an Improved Skate; and we do hereby-declare the vi'ollcm ing to be a full, clear, andexact description of. the same Our improvements,whicb: are fully described hereafter, have for their-objects adjustability of the skate to boots of difi'erent sizes, the yielding of the skate (which has two runners) so that it will accommodate itself to the movements of the wearer's foot, and ready means of attaching the skate to the boot without the aid of straps and other inconvenient fastenin'gs.

In order to enable othersskilled inithe art to make and use onrinvention, we will now proceed to describe its construction and operation, reference being bad to the accompanying drawing, which forms a part of this specification, and in which- I Figure 1 is a side View, partly in section, of our improved skate.

The rest for the foot in our improved skate consists of the heel-plate A and sole-plate A,the former overlapping the latter, as seen in figs. 1 and 3. To the heel-plate A is secured the runner B, a projection, a, on which fits snugly, but so as to slide and vibrate freely in a slot in aprojection, b, of a. runner, B, secured to the sole-'platc-A. The plates are secured together by two bolts, e e, fitting snugly in holes in the plates A, butpassing through slots ff in the plate A, so that, after loosening the thumb-nuts with which the bolts are provided, the plate A is at liberty to be moved to and fro over the plate A. Inaddition to the bolts, the stem of a stud, z, is secured to the upper plate A, and passes through a slot in the plate A, which is underlapped by the head of the stud, thereby assisting to maintain the two plates in proper contact with each 0thcr,.wi-th0ut preventing themovcment of one pluteiindependent of the other, when such movement is necessary, -and is per mitted by loosening the thumb-nutof the bolts e. A stud, m, is secured to the heel-plateaA and "two similar studs, n and n, to the sole-plate A.

The boot is prepared in the following manner for the attachment of the skate: A'plate, D, is let into and properly secured to the heel of the boot, which is recessed above the plate for the free movement to and fro of the head of the stud.m, this head being passed through the holed of the plate, and the stem of the stud passing into the recess 10, which communicates with the said hole (Z, so that the head of the'stud will overlap the plate, and thefskate be thereby secured to the heel. A plate, F, is let into andisecured to the'sole of the boot, near the toe, and in this. plate are twohole's, cl d, of a character similar to those-in theplate D, these holes being adapted to the reception and retention of the studs n and n.

The above-described skate is applied to the boot in the following manner: It will be observed that-the holes ti, in the plate E of the boot, arefso situated, thereverse of each other, that before the studs can enter the enlargedportions of the holes, the skate must be held in the inclined position-shown by dotted lines, (fig.

in respect to the sole of the boot. After the studs have been introduced, however, the skate is turned, so as to coincide with the boot, this act of turning the skate causing the stems of the studs to enter the narrow portions of theholes .in the plate, and the heads of the studs to overlap the same. The'iront end of the skate having thus been secured to the sole of the boot, the heel-plate A is so adjusted that the head of the studm will enter the enlarged portion 01 of the hole'iu the plate D, after which the heel-plate A is moved back, until the stem of the stud enters the narrow portion 1;. of, the hole in the said plate D, when the thumb-nuts h are tightened, and the skate is firmly secured to the boot. The method'o'f removing the. skate wili be readily understood without description.

There are several advantages in onrimprovcd skate, which may be referred to as follows: First, it can be applied to boots of diflerentsizes, owing to the longitudinal adjustabilityof one plate in respect to the other; second, the only connection between the two runners being the thin elastic plates, the said runners can move independently of each other, and accommodate themselves to the movements of the wearers foot; third, the attachment of the skate to the boot may be accomplished with rapidity; and, fourth, the attachment is secure.

- Instead of using two plates, A and B, one to overlap the other, one elastic plate only may be used as a foot-rest, and for connecting the two runners together, in which case the stud m may be replaced by a bolt, G, arranged to slide in a slot in the plate A, the head of the bolt, after it has been moved back from the enlarged to the narrow portion of the hole in the plate D, overlapping thesaid plate, in which position the bolt is secured by a-thumb-nut, is. When the skate has to be detached from the boot, the thumb-nut 7c is loosened, the bolt drawn forward, until it can be released from;the plate D. p The skate is then depressed at the heel, and turned laterally, until its studs n and ncan be released fromthe plate E We claim-as our invention, and desire to secure by Letters Pittent- 1. A skate, having an elastic foot-plateandtwo runners, arranged to move independently of each other in a vertical direction, but to guide each other laterally, all substantially as and for the-purpose herein set forth.

2. Securing a skate to a boot solely by studs on the skate, adapted to holesin plates on the sole and heel of the boot, substantially as described.

3. The sole-plate A, and its runner B, in combination ,with the heel-plate A" and runner B, when the said plates and runners are rendered adjustable, to suit boots of different sizes, substantially in the manner described.

4. The studs n at, either fixed to or arranged to slide on the foot-plate of the skate, near the toe, in combination with the plate E on the :boot, and holes 50 formed and arranged therein as to admit and retain the said studs, substantially as specified.

5. Thestud 1n, in conjunction with a plate, D, on the heel of the boot, the said plate having a hole of the character described, into which hole the head of the stud can be introduced, and in which it can be secured, either by moving the plate to which the stud is attached backwards, or by moving the stud itself in a slot ,in the plate, all substantially as specified.

In testimony whereof, we have signed our names to this specification, in the presence of two subscribing witnesses.
